Precise and complete discharge type seed discharge mechanism

Abstract

The invention provides a precise and complete discharge type seed discharge mechanism, which comprises a seed discharge disk, a seed box and a seed protection plate, wherein the seed box is arranged above the seed discharge disk, the seed protection plate is arranged between the right side of the seed box and the bottom end of the seed discharge disk, the surface of the seed discharge disk is provided with a seed groove and a concave groove, an electromagnet is fixedly connected below the interior of the concave groove, a magnet is movably connected above the electromagnet, a blocking sheet isfixedly connected above the magnet through a movable rod, a pressure varistor is arranged above the blocking sheet, the electromagnet has an N pole above, and the magnet has an N pole above. According to the present invention, the precise and complete discharge type seed discharge mechanism overcomes the disadvantages in the prior art, and has characteristics of reasonable design and compact structure; by arranging the electromagnet, the magnetism of the electromagnet below the seed discharge disk is enhanced when the pressure resistance on the pressure varistor positioned above the seed discharge disk is reduced, and the magnet downward moves through the principle of the repulsion with the same natures, such that the seed in the seed groove can be precisely sowed into the seed hole through the downward movement of the blocking sheet.

Description

technical field [0001] The invention relates to the technical field of agricultural planting machinery, in particular to a precise row-type seed-discharging mechanism. Background technique [0002] Seeding is a fundamental part of agriculture. The quality of sowing will affect the level of emergence rate in the future. With the development of modern technology, the technical level of seeders has also been further improved. In particular, the current precision seeder has the advantages of saving good seeds, eliminating the need for thinning, and evenly distributing the plants in the precision sowing field to achieve reasonable dense planting, which is beneficial to the growth of seedlings. At the same time, precision broadcasting also has the effects of saving time, labor and increasing production. Therefore, precision seeding has become the main trend now, and its key component is the seed meter. [0003] At present, known planting machines such as domestic ordinary seed...

AI Technical Summary

Problems solved by technology

[0003] At present, the known planting machines such as domestic ordinary seeders and air-suction seeders have always had the problem that the seeds are not discharged cleanly in the seed tank, so that the seed filling rate is low, resulting in uneven sowing and affecting the emergence of seedlings.
